How many electrons can the first shell hold?
Think about the first level in the structure.
What term describes the outermost electrons?
These electrons are key to chemical reactions.
What is the maximum number of electrons the third shell can hold?
Think of the electron capacity pattern.
True or False: Valence electrons are found in the innermost shell.
Recall the definition of valence electrons.
Explain the relationship between electron configuration and an element's position in the periodic table.
Consider how elements with similar configurations are grouped.
Given an element with the electron configuration 1s² 2s² 2p⁶ 3s² 3p⁵, identify the element and predict its reactivity.
